Commitments and Contingencies Disclosure [Abstract] |
Commitments | Commitments San Diego Leases In April 2013, the Company entered into a lease for office space located in San Diego, California. The term of the Lease commenced on December 1, 2013. The initial term of the Lease is ten years, with a right to terminate on December 1, 2019, subject to specified conditions. In June 2015, the Company amended the lease for this space to increase the total leased space and occupy the entire building. The commencement of the amended lease was in January 2016 and increased monthly lease payments to range from free rent to $99,000. The Company has capitalized $822,000 of tenant improvements within fixed assets on the consolidated balance sheet related to this additional space, and has recorded a corresponding increase to deferred rent. In October 2016, the Company entered into an office lease (the “new Lease”) for a second property located in San Diego, California. The total space under the new Lease is approximately 51,000 square feet. The Company is using the facility for office, manufacturing and research and development purposes. The term of the new Lease commenced on June 1, 2017. The initial term of the new Lease is ten years, with a right to terminate on November 30, 2023, subject to specified conditions. The base rent adjusts periodically throughout the term of the new Lease, with monthly payments ranging from free rent to $95,000, with a portion of the rent abated for certain periods during the first two years of the initial term. In addition, the Company is obligated to reimburse the landlord its share of operating and other expenses, and has paid a security deposit of $95,000. As of December 31, 2017, the Company has capitalized $2.3 million of reimbursable tenant improvements to the new office which has been recorded as a leasehold improvement within fixed assets on the consolidated balance sheet, offset by a corresponding amount recorded in deferred rent. Plymouth Meeting Lease and Sublease In March 2014, the Company entered into a lease (the "Lease") with a publicly owned real estate investment trust for office space located in Plymouth Meeting, Pennsylvania. The Company occupied the space in June 2014. The initial term of the Lease was 11.5 years. The base rent adjusts periodically throughout the term of the Lease, with monthly payments ranging from free rent to $58,000. In addition, the Company is obligated to reimburse the landlord its share of operating and other expenses and a property management fee, and has paid a security deposit of $49,000. In July 2015, the Company amended the Lease to increase the total leased space. The commencement of the amended Lease was in the first quarter of 2016 and increased monthly lease payments to range between free rent to $80,000. In June 2017, the Company entered into a sublease (the “Sublease”) for additional space in its current office in Plymouth Meeting, Pennsylvania. The total additional space subject to the Sublease is approximately 30,000 square feet, which the Company intends to use for office purposes. The Sublease commenced on October 1, 2017 and will end on June 30, 2027. The base rent adjusts periodically throughout the term of the Sublease, with monthly payments ranging from $75,000 to $90,000. In addition, the Company is obligated to reimburse the sub-landlord its share of operating and other expenses. In December 2017, the Sublease was reassigned by the sub-landlord back to the landlord, with no change in the underlying terms of the Sublease. In June 2017, the Company entered into a second amendment to the Lease to extend the lease term and term of the Sublease through December 31, 2029. In connection with the second amendment, the Company will pay the landlord an additional security deposit of $75,000. Total monthly rent payments for the additional term will range between $173,000 and $179,000. The Company has capitalized $2.6 million of tenant improvements to the Plymouth Meeting office within fixed assets on the consolidated balance sheet, offset by a corresponding amount recorded in deferred rent. Rent expense was $2.4 million, $1.6 million and $1.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. Future minimum lease payments under non-cancelable operating leases as of December 31, 2017 are as follows:
Year ending December 31, |
2018 | $ | 3,251,000 |
2019 | 3,756,000 |
2020 | 3,891,000 |
2021 | 3,979,000 |
2022 | 4,052,000 |
Thereafter | 19,975,000 |
Total | $ | 38,904,000 |
In the normal course of business, the Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of the Company's obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these types of agreements have not had a material effect on its business, consolidated results of operations or financial condition.
